Question about Throttle Position Sensor

I remember when I had my Mustang GT, that one of the free mods you could do was adjust the TPS voltage by loosening and turning it a little bit and it would give better throttle response. Are you able to do this on the Focus as well?

Nope. Once you get the tabs aligned properly, it only bolts in one position.

For the mustang it only bolted in one position also. But if you loosened the screws and put some pressure on it while tightening it back down it would adjust it slightly. I don't recall what the voltage was set at but by tapping into the wire while tightening it down you could see that it was changing and gave better response.

Interesting...

I'm not sure why the throttle response would be any better, probably screw up your idle speed though. That's if your ECU didn't adjust after an OBD cycle or two.

I'm speculating here.....

It adjusted the idle speed more than likey, hence the feel of quicker response. Anything over 05 has diff set up as well i think.
